人造夜光宝石的结构研究及其发光机理——以“庆隆夜光合成发光宝石”为例

Study on Structure and Luminous Mechanism of Artificial Luminous Gem——“Qinglong Luminous Gem” for Example

摘要: 以碱土硼铝酸盐为基质, 添加稀土元素Eu作为主激活剂, 并添加适量的辅助激活剂, 人工制备了一种具有特殊晶格结构的高亮度夜光宝石, 它一次吸光后持续发光可达60~70 h, 被命名为“庆隆夜光合成发光宝石” (简称“庆隆夜光宝石”), 于2003年获得中国发明专利。简述了“庆隆夜光宝石”的制备方法及其基本特征, 对其结构进行了研究, 并对其发光机理进行了探讨。为了消除大众对“庆隆夜光宝石”有无放射性的疑虑, 对其进行了放射性安全检测。

Abstract: Based on the matrix of alkali-earth-boroaluminate, the luminous gem with the special crystal structure is artificially manufactured, doped with activator of rare earth element Eu and assistant-activator in a proper amount.The artificial luminous gem could glow for 60 to 70 hours continuously when it absorbs some light.It is named as "Qinglong artificially synthesized luminous gem" (short for "Qinglong luminous gem"), which was acquired the Chinese invention patent in 2003.The manafacturing method of the gem and its gemmological characteristics are described briefly and the crystal structure is studied.The luminous mechanism of "Qinglong luminous gem" is also discussed. In order to eliminate the worry about its radioactivity for people, safety-radioactivity examination is performed.
